I couldn't care about any of the characters. I can't say exactly why, the writing was grammatically fine and made sense, and I'm not one of those "anti college game" people, in fact I usually love those.
I know this isn't terribly descriptive, best way I'd put it is this feels like a renpy AVN made by an AI bot. Like everything that should be there IS there, but it just feels hollow, empty, like procedurally generated.
And I extend this to everything: The artwork isnt bad, it isnt great, it's just kinda.... there. The way the girls look and talk isn't bad, nor memorable, they're just ...there. I don't remember the animations being great, nor atrocious, they're just ....present.
Overall, if you're looking for a starter game to introduce yourself to harem-style games, I guess this is fine, and you won't come away thinking it's awful, but you probably wont feel very fufilled either.
